A METHOD OF MIGRATING VIRTUAL MACHINES

A method of migrating virtual machines (300, 400) is provided, the method (300,400) including the steps of collecting input/output data of a plurality of hosts over a period of time (301), storing the collected data into a time series database for a predetermined period, building a forecast model using the stored data, predicting a subsequent input/output data within a margin of error using the forecast model, comparing actual input/output data with the predicted data, registering data that falls outside the predicted data as an anomaly and clustering data into normal and abnormal data clusters, tracing the anomaly back to a relevant host, wherein the virtual machines located in hosts with anomalous data are migrated out to other hosts (303) based on analysis of collected data (302) using the steps above and a host selection sequence determined by closest nodes to a source host.
